CABLE-GRIP.

SPECIFICATION forming part of 'Letters Patent No. 757,724, dated April 19, 1904.

Application inea August 15.71903.

To all wi/'om/ t may concern:

Be it known that I, THOMAS J. COOK, aciti- Zen of the United States, residing at Searles, in the county of Tuscaloosa and State of Alabama, have invented a new and useful Cable- Grip, of which the following is a specificati on.

rIhis invention relates generally to cablegrips, and more particularly to a cable-grip to be used in connection with mining-cars; and the object of the invention is to provide an VeX- ceedingly simple and durable construction of grip which can be quickly and easily operated.

With this object in view the invention consists in the novel features of construction, combination, or arrangement, all of which will be fully described hereinafter and pointed out in the claims. i

In the drawings forming part of this specification, Figure 1 is a perspective view of a cable-grip constructed in accordance with my invention and applied to the end of a miningcar. Fig. 2 is a transverse vertical section of the grip. Fig. 3 is a sectional elevation, and Figs. 4, 5, 6, 7, 8, and 9 show details of construction. Y

Cable-grips as ordinarily constructed for use upon mining-cars have been made of castiron, and when broken it has been extremely dill'icult to repair or mend them. All or' theY parts of cable-grip are therefore constructed oi' wrought metal, and in carrying out my invention I employ a draw-bar A, which is made of channel-iron and bent horizontally pon itself, the bowed portion projecting outwardly from the car, as most clearly shown. A plate B is fastened to the end of the drawbarV and hangs downwardly therefrom, the lower end of said plate carrying a shoe C, which is grooved longitudinally, as shown at O', for the purpose of receiving the cable D. A gripping-shoe E, having a longitudinal groove E', is arranged to work in connection with the stationary shoe O for the purpose of gripping the cable, said gripping-shoe being integral with the plate E2, the ends of which are bent back, as shown at E3, embracing the side edges of the plate B and serving as a guide for the gripping-shoe E. The grippingshoe E is moved up and down by means or' a rod F, the lower end F' turning loosely in a serin'nofisata on meer.)

recess F2, produced in the plate E2, said end being heldin place by means of a clip F3, bolted to' the plate B above the enlarged Vend of the rod. The upper, portion of the rod is threaded, as shown at F4, said threaded portion working in a nut G, held between the members of the draw-bar, and a double crank or handle H is attached to the upper end of the rod and by means of which the rod is rotated for the purpose of raising or lowering the gripping-shoe. A plate I is bolted to the drawbar upon the side Aopposite the plate B, the same bolts serving to secure both plates. The nut G is held in place by means of a bolt K, passed vertically through the horizontal portions of the draw-bar.

y It will thus be seen that I provide an eX- cecdingly simple and durable construction of cable-grip, and in order to grip or release the cable it is necessary to turnthe handle H so as to raise or lower the gripping-shoe.

' Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-y A f l. A cable-grip comprising a U-shaped draw-bar, a nut secured between the-members of said draw-bar, a plate connected to one side of the draw-bar and depending therefrom, said plate terminating in a iiXed shoe, and a gripping-shoe slidable upon the depending plate, the rod carrying said gripping-shoe, said rod being threaded and working through the nut carried by the draw-bar, as set forth.

2.- A cable-grip comprising the U-shaped draw-bar, a .nut arranged between the members of the draw-bar, a plate secured to the forward end of the draw-bar and depending therefrom, said plate terminating in a iXe-d shoe, a movable shoe integral with a plate having its ends bent around the first-mentioned plate, a rod pivotally connected to the movable shoe, and threaded for a portion of its length, said threaded portion working through the nut, all of said parts being arranged and adapted to operate'substantially as described.
